Abstract
An air damper comprises a cylinder having first and second openings at both ends, a piston that moves in the cylinder, a piston rod coupled to the piston and moving in and out at the first opening of the cylinder; and a cap positioned at the second opening of the cylinder. The piston rod has a continuous outer wall and an opening extending along the longitudinal axis of the rod. The cross-sectional view of the piston rod taken along a plane perpendicular to the longitudinal axis is an inverse U-shape, an inverse V-shape, a C-shape, or the like. The piston rod has a fixing ring at the leading end. A plane containing the opening is perpendicular to a plane defined by the fixing ring. The piston rod is fixed to a glove box so that the opening faces down.
